Description

Technical Field

[0001] The present invention relates to the technical field of optical detection, and in particular to a detection device for traffic roads. Background Art

[0002] In the field of traffic road safety monitoring, visibility is one of the core meteorological parameters that affect driving safety. Visibility monitors based on the principle of optical scattering are widely used in existing technologies. They transmit a light source and receive scattered light signals to invert visibility values. However, such devices have significant drawbacks when exposed to outdoor environments for long periods of time: 1. The surface of the monitoring lens protective glass is easily contaminated: The surface of the optical lens protective glass at the detection end is easily contaminated by dust, rain, snow, insects, and exhaust oil, resulting in optical path attenuation or signal distortion. For example, the long-term deposition of PM2.5 particles on the surface of the lens protective glass will form a diffuse reflection layer, causing systematic deviations in the measured value. 2. Insufficient mechanical protection: Traditional equipment lacks all-weather protection design. Extreme weather (such as hail and sandstorms) may directly impact the detection window, causing physical damage to the optical components. At the same time, when contaminants appear on the surface of the monitoring lens protective glass, it is necessary to manually wipe the lens protective glass surface.

The transmission screw 207 in the rotating state drives the first slider 206 through the external thread groove to drive the U-shaped plate 204 and the rubber plate 203 to move toward the position of the sealing cleaning plate 201. The rubber plate 203 is in a stretched state during the movement; The angle adjustment device 210 inputs a stable operating current to drive the sealing cleaning plate 201 to rotate ninety degrees relative to the position of the second slider 208. At this time, the geometric center point of the sealing cleaning plate 201 and the geometric center point of the lens protection glass of the monitoring terminal 103 are on the same plane.
